Assertion (A): In a fluid, the rate of deformation is far more important than the total deformation itself. Reason (R): A fluid continues to deform so long as the external forces are applied
Both A and R are individually true and R is the correct explanation of A
Both A and R are individually true but R is not the correct explanation of A
A is true but R is false.
A is false but R is true

negative
unpredictable
positive
zero
Which of the following statements is relevant ?
Fluid deforms continuously under the action of shear stress of even very low magnitude
Fluid deforms under constant shear stress
Fluid can sustain shear stress when at rest
Fluid does not deform continuously under the action of shear stress
In the context of fluid mechanics, which of the following statements is Incorrect ?
Fluid continues in motion under the application of shear stress
Fluid does not deform continuously under shear stress
Fluid cannot sustain any shear stress when at rest
Fluid deforms under very small shear stress
Which of the following is the basic property of fluid ?
Never regain its original shape on release of shear stress
It undergoes a definite deformation
More compact in structure
Can resist tangential stresses in static condition
Fluid is a substance that :
cannot be subjected to shear forces
always expands until it fills any container
has the same shear stress at a point regardless of its motion
cannot remain at rest under action of any shear force
